The emissions reduction technology requires no action by the operator. The system uses Caterpillar’s after-treatment solution with the addition of selective catalytic reduction (SCR). SCR utilizes diesel exhaust fluid (DEF), which can be filled from ground level when the machine is fueled.

A new standard economy (ECO) mode can be turned on to help save fuel by reducing engine speed so the machine works in a more efficient range. The average fuel savings is up to 10 percent, depending on the application, Caterpillar says.
